A buyers agent finds and negotiates the purchase of a property. A mortgage broker finds and negotiates the loan behind it. They are not competing services and they are not interchangeable, yet plenty of buyers assume one professional can do both jobs. Knowing where each role starts and stops can save you from a gap nobody is covering.
What a buyers agent actually does
A buyers agent works exclusively for the purchaser, searching for properties, assessing value, and negotiating on price and terms at auction or through private treaty. In Australia, a buyers agent typically charges a fee ranging from a fixed amount around $10,000 to $15,000, or a percentage of the purchase price, often between 1% and 2.5%, depending on the level of service.
Their focus sits entirely on the asset itself, whether that is an owner-occupier home or an investment property. A good buyers agent brings comparable sales data, off-market opportunities through their networks, and negotiation experience that can offset their fee, particularly in a competitive market or for a buyer unfamiliar with a specific area.
What a mortgage broker actually does
A mortgage broker works with you to find and arrange finance for a property purchase, comparing loan products across a panel of lenders that can range from a handful to more than 30, depending on the brokerage. Brokers assess your income, expenses, and financial position to determine borrowing capacity, then match you with a lender and loan structure suited to your circumstances.
Do mortgage brokers charge borrowers a fee like buyers agents do?
Most residential mortgage brokers in Australia are paid by the lender through a commission once a loan settles, rather than charging the borrower directly. Some brokers charge a fee for complex commercial or specialist lending scenarios, so it is worth asking upfront how a broker is remunerated before engaging their services.
Brokers are bound by a best interests duty, a legal obligation introduced in 2021 requiring them to act in the client’s interest when recommending a loan, rather than simply the option that pays the highest commission. This duty does not extend to buyers agents, whose regulation and licensing requirements differ by state and focus on property transactions rather than credit products.
Where the two roles overlap and where they do not
Both professionals can be engaged for the same purchase, and many experienced property buyers use both, particularly for investment purchases where speed and accuracy matter. A buyers agent typically gets involved earlier, helping identify and secure a property before finance is finalised, while a broker’s work usually intensifies once a property is identified or under offer, arranging pre-approval and then formal approval.
Where confusion often arises is around negotiation. A buyers agent negotiates the purchase price and contract terms with the seller or selling agent. A broker does not negotiate property price at all. Instead, a broker’s negotiation happens with lenders, over interest rates, fees, and loan features. Assuming one professional handles both conversations can leave a genuine gap in a transaction.
Why the sequencing matters for a smooth purchase
Getting finance pre-approval sorted before engaging a buyers agent, or at least in parallel, gives a clearer picture of borrowing capacity and price range before searching begins. A buyers agent working with an unrealistic budget wastes time inspecting properties that are ultimately unaffordable, while a broker working without a clear purchase timeline may build a loan structure that does not suit how quickly a buyers agent expects to move.
For time-poor buyers, particularly those purchasing an investment property interstate or without local market knowledge, coordinating a buyers agent and a broker who communicate directly with each other removes a significant amount of friction. Sharing timelines, contract conditions, and finance clauses between the two professionals reduces the risk of a settlement date being missed because one side was not aware of a deadline the other was working toward.
What to ask before engaging either professional
For a buyers agent, ask about their fee structure, whether it is fixed or percentage-based, what areas and property types they specialise in, and whether they have existing relationships with agents in your target suburb. For a broker, ask which lenders are on their panel, how they are paid, and whether they have experience with your specific situation, whether that is self-employed income, an investment portfolio, or a first purchase.
Neither service is compulsory, and plenty of buyers successfully purchase property without either. But for buyers who value speed, negotiation leverage, or simply do not have the time to research a market and a lending panel simultaneously, understanding what each professional actually does before engaging them leads to a far smoother purchase.
Key Takeaways
- A buyers agent searches for and negotiates the purchase of a property, while a mortgage broker arranges and negotiates the finance behind it.
- Buyers agents typically charge $10,000 to $15,000 flat or 1% to 2.5% of the purchase price, while most residential mortgage brokers are paid by the lender rather than the borrower.
- Mortgage brokers operate under a best interests duty when recommending loans, a legal obligation that does not apply to buyers agents.
- A buyers agent negotiates property price with the seller. A broker negotiates loan terms with lenders. Neither replaces the other.
- Sorting pre-approval early, alongside or before engaging a buyers agent, helps both professionals work to a realistic budget and timeline.
- Asking about fees, panel size, and experience upfront with either professional helps set expectations before a purchase begins.
